Buster Martin - UK's oldest employee?

Buster Martin, possibly the UK's oldest working employee having been born in 1906. He works as a part time van cleaner for the plumbing firm, Pimlico Plumbers, in London - cleaning their fleet of vans. He came to media fame in 2007 having fended off an attempted mugging. However further newspaper stories have questioned whether he was older than 100 years in age. Photographed in 2007.
